Abstract [en]

Industrialized building laid the foundation of modern building techniques and has developed into a prefabricated building. With better knowledge of materials and working methods, engineers have learned tolerance, fit, and dimensions that are most important parameters for assembling prefabricated elements. In this study, we treat the development of prefabricated building during the 21st century and what needs to be improved, how we create an efficient construction industry that can contribute to increased Swedish growth and productivity. From the result we can determine if prefabricated houses are the future of construction method. Houses in wood are by far the largest in the prefabricated construction and are now 90% of new building. As expansion develops technology and now we build eight-story multi-family homes in wood. The prefabricated building has moved most of the work to the factory where, in a controlled environment produce finished elements which are produced in optimum conditions. This means that construction moisture in the materials no longer exists and all operations can be performed covered. The development has also led to significantly shorter construction times and under right conditions up to 80% of the time can be saved. Above all, the construction method requires less storage and is ideal in densely populated areas but requiring major demands for logistics and deliveries.
